What is the best approach to deliver low temperature and low carbon heat networks?

Can heat consumers enjoy affordable, reliable and low carbon heat? Can heat suppliers lower capex and opex spends and also deliver excellent heat network performance?

What options are out there?

Demand side response

The is about balancing the local grid through embedding flexibility into the design of heat and power usage. As a result the energy required to meet actual demand is minimised.

Fabric first upgrades

This may include fitting insulation or double-glazed windows. These are often quite invasive and disruptive for residents and relatively expensive as a consequence.

Dynamic real-time control

This is managing the energy (the heat) in response to actual conditions and targeting specific return temperature requirements. As such, it is an intervention that is dealing with control, therefore an automatic and ongoing positive impact.

Heat source selection & specification

We can fit a new heat source technology but unless we create the conditions, delivering low return temperatures, it may sit idle. For example, quite a few Gas CHP units have been installed in the last twenty years, as a low carbon measure, but have never been turned on.


At Minibems we proportionally control the heat going into each heat consumer – matching heat supply with real-time demand by varying the flow rate. Our next webinar will look at:

  • The difference between real-time control responding to real-time conditions versus model-based control strategies
  • Why applying dynamic control authority is a critical element of enabling low temperature and therefore low carbon heat networks
  • How heat networks without control at the point of use have only limited control over the whole of the heat network
  • How using data in real-time solves real world problems

A Minibems heat network is over 70% efficient which is well above the average efficiency of heat generated to heat consumed. Typical heat networks are inefficient as they are over-delivering heat most of the year because the controls are set to operate as if it were always cold outside.

There is much less over supply of heat because the Minibems HIU is a Smart HIU – with a dozen components connected online giving real-time control, monitoring and diagnosis. As a result:

  • Central boiler plant no longer cycles
  • Gas CHP no longer derate
  • Heat pumps and other low temperature heat sources are now viable all year round
  • Heat network are decarbonised from day one of operations

Heating is the UK’s biggest source of carbon emissions. Right now, 500,000 UK homes are connected to heat networks that are supposed to be more efficient and generate fewer carbon emissions, but they are wasteful from the point of installation.
